MMX Performance G90 / G99 M5 Lowering Spring Set

The MMX Performance Lowering Spring Kit is one of our best-selling upgrades, and it’s easy to see why. Renowned for delivering the ideal balance of sharper handling, improved stance, and everyday comfort, it remains one of the best first modifications for the BMW G90 M5 and the new G99 M5 Touring.

By lowering the car’s center of gravity, the kit delivers a meaningful improvement in the way both platforms drive. On the G90 M5, ride height is reduced by approximately 25mm at the front and 20mm at the rear. On the G99 M5 Touring, the drop is 25mm at the front and 15mm at the rear. In both cases, body roll is noticeably reduced, turn-in feels sharper, and overall chassis dynamics are significantly improved, all while maintaining the comfort and refinement expected from BMW M.

Carefully selected progressive spring rates ensure that low-speed ride quality remains smooth and composed around town. As speeds increase, the chassis feels lighter on its feet, more direct, and far more responsive through corners, exactly what the M5 platform benefits from without sacrificing daily usability.

Visually, the transformation is just as impressive. The reduced ride height gives both the G90 M5 and G99 M5 Touring a more aggressive, purposeful stance without looking excessive or compromising practicality.

Going any lower or stiffer risks upsetting the factory balance, with mismatched damping and reduced spring travel leading to a harsh, unsettled ride. MMX Springs are engineered specifically to work in harmony with both static and Adaptive M dampers, preserving ride quality while enhancing performance.
